BOILER-THEE CLEANER.

Application illedlugust 16, 1915.

To all whom it may concern:

it known that l, Josnrrr C. BOWMAN, a citizen of the United Eitates, residing at Boy, in the county of Weber and State-of Utah, have invented certain new and useful improvements in Boiler-Tube Cleaners, of

, which the following is a specification.

My invention relates to improvements in boiler tube cleaners, and one object of my invention is the provision of a cleaner which will. adapt itself to tubes of different diameters.

Another object of my invention is the provision of a boiler tube cleaner, wh ch "5 permits of the easy removal of the blades for the purpose of repair or renewal.

Another object of my invention is the g Yision of a boiler tube cleaner which will emove the scale in a thorough, rapid and eihcient manner.

Another object of my invention is the provision of a boiler tube cleaner of the character and for the purpose described, which will be simple of construction, inexpensive to manufacture and one which will practical and efficient in every way.

With these objects in view my invention consists of a boiler tube cleaner, embodyingnovel features of construction and combination of parts for service, substantially as shown, described, and particularly defined by the claim. I

Figure 1 represents a side elevation of a boiler tube cleaner constructed in accordance with and embodying my invention. Fig. 2 represents a central sectional view thereof, and Fig. 3 represents a front end elevation thereof.

lin the drawings: the letter A, designates the handle, of proper length, having its in nor threaded end B, engaging the threaded end C, of the head I), said head having the two flaring compressible limbs E, formed with the slot 15, to receive the inner fiat ends G, of the blades l-l.

The blades H, are of curved form to provide the forward cutting edges H, having their flat ends secured by the clamping screws J, passing through the hole K, in the end G of the blades H.

of the blades H are the studs L, around wh ch coils the ends of the spring M, which spring forces the two blades apart, therebv causing the cleaner to fit snugly. U

lln inserting the cleaner in the tube the two blades are drawn together and after hemg inserted are released and the spring forces the blades outward thus insuring an effective and efficient cleaning of the tube.

It will be noted that l provide a boiler tube cleaner that will be simple, durable, eiliclent and practical in every respect.

The shape of the blades causes them to properly engage the tubes and cut the scale therefrom with ease and quickness and the connection of the blades with the head and the arrangement of the spring allows the blades to adjust or accommodate themselves to the tubes to insure proper fit and ease of movement. Also the manner of connecting the blades to the flaring limbs permits the blades to be quickly removed and applied, and generally in every respect the device will prove efficient, useful and practical.

It will be noted that theblades have a spring disposed between them and that they have when together a circular cutting edge and terminate in a thin edge which can be easily applied to and removed from the head and that the tapering or thin edge gives a proper amount of resiliency to the blades in the cleaning process. Also that the blades JOSEPH C. BOWMAN.
